LAS VEGAS, USA (AVING Special Report on 'NXTcomm 2008') -- <Visual News> Avago Technologies, Infinera and Ixia are collaborating on live demonstrations that send 100 Gigabit Ethernet(100 GbE) traffic over a long-haul network from Infinera's booth at NXTcomm08 in Las Vegas June 17-19th.

The partners believe that the demonstrations of 100 GbE capability mark significant progress towards making 100 GbE products and services a commercial reality in the near future.

Ixia demonstrated an initial implementation of 100 GbE line-rate traffic generation and analysis. The traffic is handed off to a 100 GbE interface on the Infinera DTN DWDM transport system. The 100 GbE signal is then switched and transported by the DTN through a long-haul DWDM network to Los Angeles, where it will be looped back and then transported back to the Infinera booth in Las Vegas. Performance metrics will reporte from the Ixia XM2 chassis.

The growth of converged voice, video and data network services and rapid advances in computer technology and network architecture are causing bandwidth bottlenecks convincing network operators and large Internet service providers to significantly boost data speeds: 100 GbE for aggregation and core networking applications, and 40 GbE for server and storage applications.

Ixia's proof-of-concept demonstration includes the first implementation of the Multi-Lane Distribution (MLD) protocol architecture, the new 100 GbE Physical Coding Sublayer (PCS) approved as the baseline proposal just last month by the IEEE 802.3ba task force. MLD bonds multiple physical lanes into a single, logical 100 GbE link. Currently, the highest line rate commonly available for Ethernet is 10 GbE. Ixia and Infinera have been working with the 802.3ba task force from its inception and are committed to supporting efforts to reach an industry-wide standard.

Avago is demonstrating prototype 100GBASE-SR10 optical modules consisting of a 10-channel optical transmitter and receiver pair. These modules are capable of transmitting data at rates in excess of 10 Gb/s per channel, yielding more than 100 Gb/s of aggregate bandwidth. 100GBASE-SR10, the new parallel Physical Media Dependent (PMD) sublayer for 100 GbE Short Reach links based on OM3 multimode fiber, was also approved last month as a baseline proposal by the IEEE 802.3ba task force.

Infinera's 100 GbE Tributary Adapter Module (TAM) interface for the DTN takes the 100 GbE signal and puts it onto the transport network using Infinera's Digital Virtual Concatenation (DVC) protocol to send it across ten optical wavelengths at 10 Gb/s each. The TAM module fits inside an Infinera Digital Line Module (DLM), using only a single pair of photonic integrated circuits to transport the 100 GbE signal.

With Infinera's new ILS2 system, which begins shipping this summer, up to sixteen 100 Gb/s DLMs can be multiplexed onto a single fiber, allowing the transport of 1.6 Terabits/second (Tb/s) of information, with future scalability rising to 8 Tb/s of capacity. Infinera's Bandwidth Virtualization™ enables these services to be carried over current optical infrastructures with little or no optical reengineering required.
